A new opportunity to add value to packaging is the combination of low cost technologies such as printed sensors, RFIDs and printed solar cells on paper. In this way, smart packaging with following properties can be achieved:
- Printed sensors for temperature, humidity and touch monitor the environment of the packaging throughout the supply chain. They allow intelligent packaging functionality and consumer interaction.
- Light emission after activation attracts customers and provides information.
- RFID enables logging, tracking, tracing and data transfer.
- A printed solar cell on paper provides energy and can load energy storage devices such as printed batteries and capacitors to increase the range of data transfer and store logged data for a longer time.
